My jeep is an 05 wk 3.7 and yesterday i noticed it idling high when i first strted it. Normally it idles at 900-1000rpms but when its in park or neutral it idles at 2k. Anyone ever have this problem or know what it is?

Pull the codes yourself using the key dance… start in the ignition off position then turn to the on position without starting the engine, off, on, off, on then look at your EVIC and it will display the CEL codes.
